elaboration internal error (IUS61)

archive

I'm compiling and elaborating a very simple SV code, attached as svlog01.tar.gz file.
Following the compilation and elaboration code.

I got internal error for any top level design I tried to elaborate, while the compilation is error free.

Is there any issue in the compilation/elaboration flow or other (coding issue, tool issue) ?
The IUS61 versions has ben used.


Thanks

  • Any internal error is a serious problem and should be reported to Cadence Customer Support. You have a nice small testcase here, so they should be able to take care of it easily.

    The problem appears to be in the assignments:

    assign rdata_shram = (oen_shram == 0) ? shm_read : '{'bz};
    and
    shm_read = '{'bx};

    Apparently this '{'bz} syntax is ok (at least it gets by ncvlog), but I've never seen it used before. For unsized bit constants, I've always used 'z or 'x.

    assign rdata_shram = (oen_shram == 0) ? shm_read : 'z;
    shm_read = 'x;

  • Thanks for the fixing of the file shram.v. The problem is the construct '{}.
    It works also with the construct 'bz or 'bx.

    In the file swfabr.v, Isolved the issue fixing the code as following described.

    always_comb
    if(mask_gnt)
    gnt = '{default:'b0};
    else
    gnt = i_gnt;

    //assign gnt = (mask_gnt == 1) ? ('{default:'b0} ): i_gnt;


    Thanks again.

    Giampiero

  • I don't have 6.10-p001, but I will say that the swfabr.v file compiles and elaborates fine for me with 6.11-s003.
